SEWING-MACHINE ATTACHMENT.

Specification of Letters Patent.

Patented Jan. 28, 1908.

Application filed May 27.1907. Serial No. 375.798.

T 0 all whom it may concern:

Be it known that we, ANDREW EIBEN and ARPAD GYUnoso, citizens of the United States, residing at Cleveland, in the county Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Sewing-Machine Attachments; and we do declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to sewing machine attachments, all substantially as shown and described and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a front elevation of a sewing machine with our new attachment in closed or retired position therein, and Fig. 2 is a cross section of the machine and chair in closed relation as shown in Fig. 1. Fig. 3 shows a cross section of machine and chair with the chair drawn out as in use. Fig. 4 is a sectional view of the parts of machine and attachment and their connections on line 44, Fig. 3. Fig. 5 is a cross section on line 33, Fig. 3, and Fig. 6 is a cross section on line x'x, Fig. 3.

In the case of the sewing machine the machine may be of any preferred or common style having a suitable supporting frame and a more or less artistic cabinet E, and chair O comprises a suitable frame or support 2, seat 3 and back 4, and rollers or wheels 5. In this instance, the back is rigid with seat and frame. Suitable rollers or wheels 6 support the machine.

Extensible operating connection is 'made between, the chair frame and the machine frame by slotted connecting bars B, having sliding or extension engagement with both frames. The slots 7 in bars B extend practically the full length of said bars, and are each provided with a right angled flange portion 8 engaged through lon itudinal slot 10 lengthwise in bottom side rai or bar 12 of the machine frame at each side thereof, and which, in this instance, is rigidly fixed at its ends to the legs of main frame F of the machine. The flange or engaging portion 8 of said slotted bars B is approximately onethird the length of slot 10 in said bars and forms a stop for said bars in both directions of their movement, and the other portion or say half of the movement of the chair out and in is provided for by lip plate 14 at each side fixed on the forward extensions of bottom rails 17 of the seat frame by short bolts 15 extending through slots 7 in bars B and rigidly fixing plates 14 in confining relation as to said bars. Thus, it occurs as the seat is drawn out that flange parts 8 run the full length of slots 10 in bar 12 and the lips 14 with their connections 15 run the hill length of slots 7 in bars B. When the chair is retired or closed the confining lips 14 are pushed in practically over flanged engaging portions 8, which work on a lower plane than slots 7 in bars B, thus allowing such sliding in of one part over the other.

The chair rollers 5 are supported in suitable housings in the bottom rails of the chair, and when the chair is drawn out run on the floor, but when the chair is retired they are raised from the floor by rails 17 running upon respective side rests 21 and 22, therefor, Figs. 3 and 4, where theyare raised off the floor and rest till the chair is drawn out again. This leaves the machine upon its own rollers, 6, and the chair attachment is wholly out of the way and retired in all respects Its finished and uniformly designed back gives it the appearance of being part of the .machine cabinet. This provides a sewing machine with a chair which is always in place and easily moved while occupied into any preferred position for work, and which leaves the operator as free in all respects as if she occupied an independent chair. Then as said chair is to be retired within the machine it is pushed back upon its rollers until the bottom projections 24 and 25, respectively, on each of said chair bars 17 reach the respective and corresponding rests or landings 21 and 22. As these rests are reached said projections or risers 24 and 25, which are in line therewith strike the upwardly inclined surfaces of said rests and sliding thereon lift the chair bodily from the floor, as seen in Fig. 2 and. support it upon the frame of the machine.

Bottom or base bars12 besides having an open slot or channel their fulllength between the legs of frame F are of channel pattern inside, adapted to have the flanged bar B to run therein and hold its working relation thereto, and these parts are constructed for a loose fit so as to allow due freedom to the operation of the parts.

It is observed also that the extensible connections between the two objects, the chair and the machine or frame, are at the bottom of both, and that the connecting mechanism is so constructed and arranged that neither side can operate in advance of the other and that both must operate conjointly, thus making it easy for the occupant of the chair to move the chair back and forth on its rollers by a simple action of the body and with very little physical effort. Of course for type writers and desks, the seat back Would be relatively higher or a foldable part.

It will be seen also, that the chair back 4 comes flush with the front of the machine at the sides thereof and is finished in harmony therewith, so that, when closed it makes, or helps to make a complete and attractive cabinet finish for the front of the machine.

What I claim is 1. The frame of the machine having a cross-bar at each side at the bottom provided with lateral rests at each end having a top inclined surface, in combination with a chair having a bar at each side at the bot-- tom connecting the chair with the frame and provided with projections adapted to slide and rest upon said lateral rests and thereby support the chair upon said frame.

2. A machine support having a transverse channeled bar at each side at the bottom provided with laterally projecting rests at each end, in combination with a chair having a forwardly projecting bar at each side at the bottom and provided with projections at each end adapted to move upon and seat on said rests, and connecting links slidably connecting said chair bars with the bars on said machine support and adapted to limit the withdrawal of the chair. E I

3. The combination of the machine frame and the chair frame and links at each side slidably connecting said frames at their bottom, the said chair frame having side-bars extending forward of the seat and provided with projections at their bottom, and the said machine frame having inwardly extending rests ada ted to seat said projections there on and t ereby raise the chair off the floor, and the said links slotted lengthwise and having loose stop connections with said machine frame.

4. A machine support having side portions, a bar extending transversely across the bottom of each side portion, a laterally extending rest at each end of each bar, in combination with a chair adapted to enter the space between said side portions of the machine support, a bar at the bottom of the chair on each side thereof, each bar having a portion at each end thereof adapted to slide upon and rest on the top of one of said lateral rests, to thereby lift and support the chair out of contact with the floor, and slidable connections between the bars on the chair and the bars on the machine support.

In testimony whereof we sign this specification in the presence of two witnesses.
